Xmas update bug

There’s a bug preventing oscillators from being set at -1 octave. Apart from that an awesome update to one of my favourite synths on iOS.

Mac App Please?

Warmth beyond words!

It’s no joke and no exaggeration to say that this synth has an unusually warm sound and feel to it. It’s almost odd how good this synth sounds, even on the simplest patches. Yet, this is not just a typical Moog copy. It definitely has its own feel and character and if you spend some time with it, you’ll be amazed at how well it fits into a mix. Thanks.
